Hazel He, a PhD student in the Edwardson School of Industrial Engineering.

Supply chain burst into the public consciousness during the pandemic, when this little-known industrial engineering discipline was the focus of endless discussion and handwringing as critical products like semiconductors and toilet paper disappeared from industrial inventories and supermarket shelves. The new buzzword became resilience: how to reconfigure supply chains — the networks of companies that work together across the entire product development process to design, produce and deliver a finished good – to be more robust and flexible in the face of unanticipated disruption. Hazel He is tackling this challenge head-on as a PhD student in the Edwardson School of Industrial Engineering.

What is your research focus? What is it you hope to achieve?

My research focuses on supply chain resilience, particularly key materials for EV batteries. I’m investigating ways to improve supply chain resilience amidst disruptions using AI and data-driven approaches. My ultimate goal is to help nations and businesses build resilient and forward-looking supply chains that can both foresee potential disruptions and remain productive under challenging circumstances. This work is critical in strengthening global supply chain systems to ensure long-term stability and competitiveness.

What spurred your interest in this line of research?

My interest stems from my professional experience in supply chain finance. During my work in industry, I saw how supply chain dislocations could destabilize businesses, especially small and medium-sized enterprises. In today’s increasingly unpredictable world, I want to help businesses make more informed decisions about their supply chains by providing them with tools and insights to mitigate risk and navigate uncertainty. The transition to EVs presents unique challenges in material sourcing and logistics, and I wanted to use my expertise to make a difference in this critical area.

Why did you choose Purdue to continue your studies as a graduate student?

Purdue is renowned for its excellence in engineering and its emphasis on practical applications. A key factor for me was my advisor, Dr. Stephan Biller, whose extensive industrial experience and current research align closely with my focus. His mentorship and insights have been invaluable, and we share a strong synergy in our research interests. Additionally, Purdue’s connections to industry, robust research facilities and collaborative environment made it an ideal choice for me.

When did you first get interested in engineering?

I grew up in northern China, a region famous for its dairy products. My parents worked at China’s largest dairy factory and often brought me to their workplace. Watching the production lines in action — the massive manufacturing machines, the robotic arms and the tangible process of creating something — sparked my fascination with engineering. I’ve always had a strong interest in physical things I can touch and see, which led me to pursue this path.

What’s it like studying at Purdue?

Studying at Purdue has been an inspiring experience. My advisor is not only an industrial expert but also an incredibly supportive mentor. He encourages innovative thinking and provides an open research environment where I can explore new ideas. The collaborative and collegial atmosphere among students is equally enriching, as we constantly learn from and support each other. Purdue provides the freedom to pursue innovative ideas while offering access to exceptional resources.

What advice might you give to students deciding where to attend graduate school?

The decision can be challenging, but it’s important to prioritize what really matters. Consider not just academic rigor but also the environment, culture and lifestyle you’ll enjoy as a graduate student. The journey can be long and where you live and the community you’re part of can significantly influence your experience. Purdue offers a balanced combination of academic excellence and a welcoming, collaborative culture.

What about the future? What are your goals and what are you looking to accomplish in this field?

My goal is to bridge academia and industry by developing actionable solutions to major supply chain challenges. In the long term, I hope to lead initiatives that integrate sustainability, resilience and innovation into global supply chain systems. Personally, I want to continue growing and contributing meaningfully to my field.

Might you share with us a little window into your personality?

I pay close attention to both my physical and mental health. I enjoy running, swimming and cycling, which helps me stay grounded and focused. Music is another big part of my life — I play the cello and piano to recharge and express myself creatively. I strive for balance in life, always looking to grow personally and professionally.
